This application is a continuation of my application, Serial Number 136,837, led April 27, 1927.

This invention relates to vehicles and has for its object to provide an improved frame structure. it consists in certain features and elements, in combination, as herein shown and described, as indicated by the claim.

In the drawings:

Figure 1 is a view in side elevation of a rearward portion of a vehicle embodyingthe present invention, with body removed.

Figure 2 isa dicated at line 2:2 on Figure 1,y with one of the spring shackles omitted to show the radius rod connections to the axle. .Y Figure 3 is a rear end view of thevehicle,

as shown in Figure 1. v

For purposes of illustration my invention is shown in connection with a certain type of trailer vehicle, having a frame which includes a pairv of longitudinally extending f channel side members, 10, connected together in any suitable manner, and a rear end member, 11. lt will be noted that the drawings merely show the rearportion of thevehicle.

The rear end of the vehicle includes the usual 12, provided with wheels, 13,V for supporting the vehicle. A pair of spaced,

cross channels, 14, are secured to the, lower flange of the side channels, 10, substantially over said axle and the lower flanges of channels, 14, are connected by aplate, 15, towhich is secured a transversely Vextending A semielliptic leaf spring, 16, by a pair of U-bolts,

17. The ends of said'spring are perched on the axle by pivotal shackles, 18, .connected to axle brackets, 19, on said axle, as vshown in Figure 3.

fixed axle,

housing for a coupling pintle hook indicated at, 21, having its hook proper extending rearwardly beyond the rear channel, 14, to engage the draw bar of another trailer vehicle for pulling the same in a train. 7

horizontal view taken as in-V tween a pair of lugs,

The channel members, 14, also serve as ak VV-shaped brackets, 23, are secured to the y 'ff lower flange of the side members, 10, and are connected vtogether by two `transverse cross' bars, 24, disposed on opposite sides ofsaid v brackets and having their endsV extending therebeyond. These cross bars are preferably structural angle members, engaging the lower outside corners of the brackets, with the hori- Zontal legs on the bottom and extending toward each other. Each side of the vehicle 1 is provided with a step, 25, mounted for piv- Votal movement on a pin, 26, ournaled inthe upright legs of said angle crossmembers,

24, adjacent the ends. Said stepis adapted 1 l -Go to be supported in a horizontal position resting uponvsaid inwardly extending horizontalV legs of the angle members, 24. l The pivotal support of the step permits folding the same upwardly, out'of the way, as shown on the right hand sideof the vehicle in Figure 3.k

VThe step enables the operator to observe the contents in the vehicle body (not shown) and also permits raising an obj ect sufficiently high 1 to clear the body sides inloading the vehiclel i body.y Y 1 Y Y in vehicle construction' of this type it is essential that ythe axle be additionallyl connected to the frame and for this purpose I provide a pair of radius rods, 29, each having one end pivotally mounted bely from said axle adjacent the. wheels; the

Vwill be noted that thisarrangement forms a triangular truss, positioned in approximately the horizontal plane of the `axle,thus securing satisfactory 'operation in controlling axle movement duringflexure of the spring. A
